There is limited evidence on the responsiveness of the Short Form-12 Health Survey version 2 (SF-12v2) in hypertensive patients. This study aimed to evaluate both the responsiveness of the SF-12 measures in Chinese hypertensive patients.
A prospective longitudinal study was conducted on hypertensive patients managed in public primary care clinics between 2012 and 2013. A total of 583 and 431 patients were surveyed and completed SF-12v2 at baseline and at 12-month follow-up interviews, respectively. Using global rating of change scale as an external anchor, the responsiveness was assessed by linear mixed effect models, multiple linear regression models, and receiver operating characteristic (ROC) curve analysis.
SF-12v2 managed to detect negative changes among hypertensive patients in worsened general health group but failed to identify changes among hypertensive patients in improved general health group. Meanwhile, some domains of SF-12v2 detected a significant difference in difference between patients of worsened and stable/improved group and between patients of stable and improved group, but none of the domains and the summary scales reached the recommended standard of 0.7 in any comparisons in ROC analysis.
The SF-12v2 was responsive to worsening of HRQOL but not to improvements in HRQOL among hypertensive patients. The overall responsiveness of SF-12v2 in hypertensive patients is unsatisfactory. Further studies are needed to identify HRQOL measures with good internal and external responsiveness for hypertensive patients.
